lcd panel white line at the very bottom quotation

Ours is a Sony Bravia that is now over 10 years old. Several months ago we started noticing lines, especially on the left (our left) side of the screen. They’d go away after the tv warmed up. Then we started noticing it was darker on that side of the screen, but again, after the tv warmed up the screen would be normal. Then about two months ago it started getting worse and didn’t ever get completely better, even after the tv warmed up. So I watched some youtube videos that all talked about the ribbon cables becoming loose over time and to apply pressure along the top and see if that made it better, and if so, it was a loose cable and if you put electrical tape or something that would help keep the pressure, it would fix the problem. Hubby pressed along the top and sure enough, when he pressed in one spot on the left side suddenly the picture cleared up. Stayed good for about a week, then problems again, pressed again, fixed again. A week or so later, same problem, but this time when he pressed on it nothing got better.

So I decided to take the cover off and look at it better. As I was pressing on the tops of the ribbon cables that run down from the top of the frame, for a minute it got better but then suddenly there was a wide white vertical line, with a thin green one down the center of it, running down the front of the screen, and it was perfectly aligned with one of the cables. So now I still have the dark side of the screen, and some ghosting, and some lines, but now this bright white streak/line right down the front. Another weird thing is that if the whole screen is bright (like watching a show set in a snowy place) then the darkness even on the left side is basically gone, but if the scene is dark at all, that side is almost black. I don’t know if it means that particular ribbon cable is bad, or if something is loose, if things need to be replaced or what. It’s very frustrating as it’s been a great tv. Hubby wants to just buy a new one, but even if he does I would still like to try and figure out this one as it could then go in another room.

In order to indicate whether the issue is driver related or hardware related, kindly start your in Safe Mode and check to see if the issue still persists or not:

If the issue still persists, most probably the issue is hardware related and the screen needs to be replaced. To double-check it, restart your computer and enter the BIOS, if the screen has the same issue, it means the screen 100% is damaged.

However, if the issue does not exist in Safe Mode and BIOS, it means the issue is driver related and you should uninstall the display driver completely using this free DDU tool:

After that, go to the manufacturer"s official website and download then install the latest or a compatible graphics card driver or you can contact the manufacturer"s support services to provide you with a compatible driver.

So, why there are green lines on a monitor? Well, several factors might be at play if the displays attached to your PC aren’t operating correctly. It’s conceivable that your adapter or cable connection is the problem. Change the cable if it doesn’t work. If nudging doesn’t work, try another.

Throughout this post, we’ll explain why green lines occur on your display and the best techniques to remedy them. The extra information will be invaluable in fixing all of your monitor’s green lining concerns. It’s time to delve in!

There are a variety of possible causes for horizontal green lines or vertical lines on your computer screen, from outdated video card drivers to damaged ribbon cables and improper video cable connections. To determine whether the problem is software or hardware, you may examine the BIOS settings.

When you see a green line on your computer screen, you should inspect your display for any faults, including all the connectors. There might be a problem with the cable causing the monitor’s color to lose signal.

It would help if you examined the possibility that your computer has been infected with a virus or other malicious software. While this isn’t one of the most prevalent reasons for a green vertical line on the display, it’s still possible.

Faulty graphics drivers might also cause problems with your monitor’s connection to the computer. However, although this is the most common symptom, it may also be seen in the form of green lines on a monitor.

Because Windows 10 does not contain the BIOS, any horizontal or vertical striations on your display problem result from a software problem. If you don’t see any horizontal or vertical lines on your Windows 10 computer screen, this is likely a hardware problem.

It’s possible that your computer’s drivers don’t cause the flickering green lines on your display if they occur immediately after the computer has started up and not on the initial screen while the machine is starting up.

The status of “This device is operating well” indicates that the hardware failure has no problems connecting to Windows 10 once the procedures are completed.

You’ll get an error number and an explanation of the issue if the component isn’t operating correctly. The device has been deactivated and must be re-enabled to fix “error code 22,” for example.

You may also try downloading the drivers from the hardware manufacturer’s website if it doesn’t work. Make sure you’re looking at “Display adapters” (in this case, “NVIDIA GeForce 9800 GTX/9800 GTX+”) and the graphics card’s name.

This is the standard procedure to remove the green lines on the monitor, regardless of whether your motherboard is set to UEFI or a classic BIOS configuration:

It’s good to have a backup copy of all of your computer’s crucial data before you begin. Even if a BIOS update fails, the data on your hard drive is not at risk.

Making a copy of your BIOS is an excellent idea, too. Don’t miss this step if you have to perform it manually, even if it’s done automatically during an update.

The prior driver version must be installed in this case. Using the drop-down option, choose the previous graphics driver version in Download Center to download and install it.

The second case is a well-known one. It will not install updates if you shut off your computer during Active Hours. For this reason, it is necessary to either modify Active Hours or manually install the application.

Monitoring a computer’s refresh rate can help identify and correct problems with graphics performance. The monitor’s refresh rate refers to how often the screen updates its image. A slow refresh rate can cause visual artifacts, such as green lines, on the screen.

Collectively, these lines indicate that the monitor is not keeping up with the latest graphics rendering instructions. This can lead to an overall degraded experience when using the computer.

The prior driver version must be installed in this case. Using the drop-down option, choose the previous graphics driver version in Download Center to download and install it.

Knowing your screen resolution, even if you aren’t an engineer or a photographer. You can appreciate your multimedia activities better if you know what you have and what you can do. In Windows 10, you may verify your screen’s native resolution by following these steps:

The resolution may be changed by selecting a different option from the drop-down menu. You should only view content that is compatible with your computer’s capabilities.

If you purchase a new external monitor or video card, you may have to change your resolution. If you’re having problems with your monitor, the first thing you should do is check the resolution. It’s a straightforward solution to a variety of visual issues.

When you start Windows regularly, programs and services in the background may cause these conflicts. If you’re having trouble accessing Task Manager, we’ve got the answer.

The monitor cabinet should never be opened to service this item. Everything that hasn’t been stated explicitly in the user handbook should be avoided at all costs.

Do not connect the monitor to anything other than the designated power supply and HDMI cable, which should be clearly stated on the monitor label or backplate.

Ensure that the monitor is close to a working power supply. The monitor’s power cord may be yanked out of the socket with a rugged grip. Attempting to disconnect the display issue by pulling its cord will not work.

Be sure to switch off your display when not in use. A screen saver program and turning off the display when it’s not in use will significantly prolong the monitor’s life.

The cabinet’s design includes ventilation holes. These openings should not be obstructed in any way. You should never shove anything into a cabinet slot or any other aperture!

The green line of death seems to be caused by a hardware problem based on the current symptoms. If you go back in time, you may discover similar problems on non-Apple devices. This problem only appeared on OLED-display phones, to be more exact.

There may be more to the problem with water damage than just a replacement screen, but it’s typically just a matter of getting a new LCD or OLED display.

Language settings are not lost when a monitor is reset to factory settings. Your specific settings, such as contrast, brightness, and picture ratio, will need to be re-entered after a factory reset.

Due to obsolete GPU drivers, the green lines on a Windows 10 laptop are standard. Using specialist driver update tools, you may repair this problem. One of the most prevalent reasons for this issue is a malfunctioning laptop display.

Your phone’s LCD might be damaged if you don’t mend a cracked screen right away. Damage to the LCD screen might occur if dust penetrates the screen cracks. Your phone’s LCD screen might be damaged if you drop it in water or other liquid.

A faulty video connection is most likely to blame for a monitor with no signal. Connect your display and PC using a different VGA cable or ribbon cable to check whether the problem remains. If not, then your video cable is to blame for this problem. Try attaching your display to another computer to see if it helps.

That’s all about the green lines on the monitor from us. An external display with bothersome vertical lines or horizontal lines may be fixed by testing the image to determine what causes these lines on the computer monitor.

It doesn’t matter whether the computer, cable box, or any other input source is to blame; the monitor, its LCD screen, or internal hardware is to blame.

An LED-backlit LCD is a liquid-crystal display that uses LEDs for backlighting instead of traditional cold cathode fluorescent (CCFL) backlighting.TFT LCD (thin-film-transistor liquid-crystal display) technologies as CCFL-backlit LCDs, but offer a variety of advantages over them.

While not an LED display, a television using such a combination of an LED backlight with an LCD panel is advertised as an LED TV by some manufacturers and suppliers.

Unlike OLED and microLED displays, LCDs cannot achieve true blacks for pixels which are illuminated by the backlight. Some LED-backlit LCDs use local dimming zones to increase contrast between bright and dim areas of the display, but this can result in a "blooming" or "halo" effect on dark pixels in or adjacent to an illuminated zone.

The local dimming method of backlighting allows to dynamically control the level of light intensity of specific areas of darkness on the screen, resulting in much higher dynamic-contrast ratios, though at the cost of less detail in small, bright objects on a dark background, such as star fields or shadow details.

A 2016 study by the University of California (Berkeley) suggests that the subjectively perceived visual enhancement with common contrast source material levels off at about 60 LCD local dimming zones.

LED-backlit LCDs are not self-illuminating (unlike pure-LED systems). There are several methods of backlighting an LCD panel using LEDs, including the use of either white or RGB (Red, Green, and Blue) LED arrays behind the panel and edge-LED lighting (which uses white LEDs around the inside frame of the TV and a light-diffusion panel to spread the light evenly behind the LCD panel). Variations in LED backlighting offer different benefits. The first commercial full-array LED-backlit LCD TV was the Sony Qualia 005 (introduced in 2004), which used RGB LED arrays to produce a color gamut about twice that of a conventional CCFL LCD television. This was possible because red, green and blue LEDs have sharp spectral peaks which (combined with the LCD panel filters) result in significantly less bleed-through to adjacent color channels. Unwanted bleed-through channels do not "whiten" the desired color as much, resulting in a larger gamut. RGB LED technology continues to be used on Sony BRAVIA LCD models. LED backlighting using white LEDs produces a broader spectrum source feeding the individual LCD panel filters (similar to CCFL sources), resulting in a more limited display gamut than RGB LEDs at lower cost.

The evolution of energy standards and the increasing public expectations regarding power consumption made it necessary for backlight systems to manage their power. As for other consumer electronics products (e.g., fridges or light bulbs), energy consumption categories are enforced for television sets.

Using PWM (pulse-width modulation), a technology where the intensity of the LEDs are kept constant but the brightness adjustment is achieved by varying a time interval of flashing these constant light intensity light sources,

A first dynamic "local dimming" LED backlight was public demonstrated by BrightSide Technologies in 2003,Sony in September 2008 on the 40-inch (1,000 mm) BRAVIA KLV-40ZX1M (known as the ZX1 in Europe). Edge-LED lighting for LCDs allows thinner housing; the Sony BRAVIA KLV-40ZX1M is 1 cm thick, and others are also extremely thin.

LED-backlit LCDs have longer life and better energy efficiency than plasma and CCFL LCD TVs.mercury, an environmental pollutant, in their manufacture. However, other elements (such as gallium and arsenic) are used in the manufacture of the LED emitters; there is debate over whether they are a better long-term solution to the problem of screen disposal.

Because LEDs can be switched on and off more quickly than CCFLs and can offer a higher light output, it is theoretically possible to offer very high contrast ratios. They can produce deep blacks (LEDs off) and high brightness (LEDs on). However, measurements made from pure-black and pure-white outputs are complicated by edge-LED lighting not allowing these outputs to be reproduced simultaneously on screen.

Quantum dots are photoluminescent; they are useful in displays because they emit light in specific, narrow normal distributions of wavelengths. To generate white light best suited as an LCD backlight, parts of the light of a blue-emitting LED are transformed by quantum dots into small-bandwidth green and red light such that the combined white light allows a nearly ideal color gamut to be generated by the RGB color filters of the LCD panel. The quantum dors may be in a separate layer as a quantum dot enhacement film, or replace pigment-based green and red resists normally used in LCD color filters. In addition, efficiency is improved, as intermediate colors are no longer present and do not have to be filtered out by the color filters of the LCD screen. This can result in a display that more accurately renders colors in the visible spectrum. Companies developing quantum dot solutions for displays include Nanosys, 3M as a licensee of Nanosys, QD Vision of Lexington, Massachusetts, US and Avantama of Switzerland.Consumer Electronics Show 2015.quantum dot displays at CES 2017 and later formed the "QLED Alliance" with Hisense and TCL to market the technology.

Mini LED displays are LED-backlit LCDs with mini-LED–based backlighting supporting over a thousand full array local dimming (FALD) zones, providing deeper blacks and a higher contrast ratio.

LED backlights are often dimmed by applying pulse-width modulation to the supply current, switching the backlight off and on more quickly than the eye can perceive. If the dimming-pulse frequency is too low or the user is sensitive to flicker, this may cause discomfort and eyestrain similar to the flicker of CRT displays at lower refresh rates.

Then yesterday while reading an email, the screen suddenly dimmed, with hazy, streaking vertical lines bleeding out of anything light. I powered it down, waited a few minutes and restarted it. On boot up, even the Cyanogen logo was bleeding light stripes over the black background, and the icon pages were a disaster. On black background pages, the icons bleed a hazy light vertical line from top to bottom. On white background pages, just about everything is hazed out by a white foggy light.

I"ve read some other older posts about striping, and some of it sounds familiar, some of it doesn"t. Certainly there are some light purplish lines at the very top of the display, and the bottom is almost washed out in white. But nothing I"ve read is a perfect match of symptoms.

I"ve posted in the tech support thread, and now need to patiently wait out some help with my almost useless OPO. Anyone have any experience on how long this might take, and what they will do? Do they even have a stock of OPOs left to replace my phone?

I"ve been reading that they often demand users to install Oxygen (I"m running the latest OTA cyanogen), but I don"t want the Oxygen os, and to me it"s pretty clear this is a hardware issue.

But what caused this sudden problem is a complete mystery. My phone is in pristine condition in the OPO fold-case, never been dropped or even banged - I treat it like a baby. One second it"s perfect, the next it"s striping all over the display?

Does anyone think this could be possibly be anything other than a hardware issue, or have any troubleshooting suggestions (ideally without rooting or anything particularly advanced)?

I had the same problem. Did the same test and then replaced the screen. Still same results, any ideas. So far I replaced the screen, motherboard, and the inverter.

If you’ve replaced LCD, motherboard and inverter but the laptop still has the same problem with video, then I would assume the problem is related to the video cable.

I’m new to this and have only handled a few different models/brands but it seems to me that most lcd video cables have different connectors (where they connect to the motherboard). Is the connector on the back of the lcd the same so that you can swap any lcd for testing or do they all have specific connectors on the back as well?

Is the connector on the back of the lcd the same so that you can swap any lcd for testing or do they all have specific connectors on the back as well?

Different LCD screens have different connectors. If you want to test your laptop with another screen, you’ll have to remove the screen from your laptop and compare connectors.

You said the screen is black. How black is it? Can you see anything at all, maybe a very faint image? Did you test the laptop with an external monitor? Can you get see external video?

Mine is a Compaq, when I move the screen forward of backward it flickers and gives a damaged image when get my hands off of it it works well,,,, can u assist me please… and thanks in advance

Test your laptop with an external monitor and find out if the external video goes bad too when you move the laptop LCD screen. I’m just trying to narrow down the problem and find out if it’s related to the LCD screen or something else.

Hi from Italy, my brother’s notebook, an Asus L3TP L3500, has a white screen since 4 years: Many people look into it to find what’s going wrong: at the end, after many years and many repairers, this is the response:

Thanks CJ. Do you know how many different kinds of connectors there are? I would buy a cracked screen of each kind to use for testing if there were just a few different types.

I’ve got a similar problem toFathi (13) but mines an acer. When I apply pressure to the keyboard area or bend it slightly the screen goes flikery and messed up.

HI, I WAS WONDERING IF ANYONE COULD HELP ME LEARN HOW TO REPLACE MY LAPTOP RIBBON CABLE FOR MY SCREEN FOR A HP DV8000. I WOULD LIKE TO DO THIS JOB MYSELF BUT I DO NOT KNOW HOW TO TAKE APART THE LAPTOP TO DO SO.

on a HP dv4000, I can barely see windows on the black lcd screen, no backlight, with an external monitor only works if the lcd cable is disconnected from the motherboard, is the problem the motherboard? need advice……..

3. If 1 and 2 do not help and you still having the same problem, most likely it’s related to the LCD screen. If that’s the case, you’ll have to replace the screen.

This is not related to the inverter board. Most likely the repair people tried reseating connections, so it’s not connection related issue. Did they try replacing the video cable? You didn’t mention anything about the video cable.

Do you know how many different kinds of connectors there are? I would buy a cracked screen of each kind to use for testing if there were just a few different types.

Be careful when you buy a cracked screen for test. If the screen is cracked badly, it’s possible you will not get any image on this screen, so it’s not really good for test.

I’ve got a similar problem to Fathi (13) but mines an acer. When I apply pressure to the keyboard area or bend it slightly the screen goes flikery and messed up.

You can try reseating the video cable connector on the motherboard. Also, this can be a problem with the motherboard or graphics card. When you apply pressure on the keyboard, you are flexing the motherboard.

Would it be totally safe to assume that at least the same model, but different cpu speed, would be usable for testing whether a larger lcd would fry the system?

I have a c400, it has heating issue and 12 inch lcd. There is a c800 with a 15in lcd (I believe). I want to put my c400 in a totally custom case, and need to find out if a c800 lcd plug is the same as on my c400… and whether the system can take the strain of the larger panel (battery life is nothing to me)…

i Got a Problem With my toshiba Laptop When i Turn it on it Turns Like orange Pink Color N i Tried My Computer screen didnt Work either. and if U Can Help Me Fix this Problem N thank You.

I just want to thank you for your advice on making sure that the video cable is securely inserted. That fixed the white screen trouble with my HP laptop.

I have a question well i came up with an idea but I don’t know how do able it is. Is there anyway to connect the LCD of the laptop to the external VGA?

Very very good. I love your website and your kindness to share your knowledge. Do you have any idea, what book should I read, or website to learn to repair a notebook mainboard?

Can you tell me if i can test on this laptop a 14?lcd (from a nc6000). The connector on the motherboard is the same but all i have is a series of coloured lines.

My LCD is completely white, i have disassembled everything and re attached the cables, still white. Tried an external monitor and that works. Am i safe to assume the LCD panel is dead?

The only way to find the culprit is testing the laptop with another working screen. If you still have the same problem on another screen, it’s bad motherboard.

Really nice usefull information.. thanks for the nice work. I have an issue with my laptop display. the display is fine in the first half the screen and the rest of the screen is just white.. i tested external monitor and it works fine. Please advice.

Hi. I have a problem where the screen is normally white, but I get an intermittent display depending on how I move the laptop. It generally works best when I tilt the laptop backwards.

This is seemingly indicative of a faulty connection, but I’m not sure exactly where. I’ve opened-up the laptop and ensured the video cable is attached properly at both ends, but the problem persists. Is it more likely that the faulty connection is on the motherboard or in the video cable?

Usually it’s bad connection between the video cable and LCD screen. Did you try reconnecting the cable? Just remove it from the connector on the back of the LCD and then connect back.

If reconnecting the cable doesn’t help, it’s possible that you have bad cable. Could be faulty LCD and even motherboard, but I would try replacing the cable first. It shouldn’t be very expensive.

Ok guys, this is driving me nuts. I have a HP Pavilion dv6000 and it works fine. The backlight works but I do have a screen problem. The bottom third of my screen looks like a large bar code. It doesn’t display anything except a bunch of vertical lines. When I plug into an external monitor, everything is fine. Any suggestions?

Ok i know this is kind of a stupid question but could you tell me the name of the connector that would connect into the video card. I am working with an Inspiron 5100 (yes i know ancient) but i am taking the screen out and converting it to be used somewhere else anyways if you know the name please tell me.

The new screens ie LED screens dont have an inverter. I have heard that most laptop companies want to use these new screens. I still havent seen a white screen on an led yet. Thanks for the comments

Do you mean loose connection between the video cable and LCD screen? I guess it’s possible, try reconnection the cable. If no help, probably it’s the LCD screen problem.

yes that is what i was planning but i found the a way to do it but i found a cheap flat monitor so i am using that instead (less hassle), if you anyone wants to figure out how its not too bad you are just running it via a network instead a direct connect (its more like redoing the laptop and putting a program on it so it is used as a monitor instead of a laptop. but it is possible i just found a cheap monitor and am using it instead.

My screen had a one pixel vertical bar down the middle of the screen. then one day it just all of a sudden went completeley white. However,when I move the screen to certain angles It flickers back into a seeable image of the login screen before it again fades slowly to white.

I sent it in to hp for repairs, and they told me it was going to be a lcd screen replacement based ON the vertical bars that they saw. I just want to ask if its possible that the vertical bar was the catalyst that set off the entire screen breaking, as it seems that only that bar was there one day before, and one day later the screen completeley broke (without being subjected to any heat or pressure. (They are trying to charge me 450$! and I think that my case should be covered under my 3 year warranty! Especially because it was a 2k business notebook at the time of purchase)

In my case, toggling back and forth from external to internal screen I can manage to get the video back on my laptop screen. Sometimes I turn it on and it is white, some other times it is normal, and some others, I lose the video while working! Any ideas on that? Fiddling around with the screen, repositioning it or moving it in anyway does not bring the video back.

I have a similar conundrum. The Toshiba Satellite A105 started with a white screen now – nothing at all. I read to try pressing on the outer edges of the LCD screen – no change. I connected it to an external monitor and it worked great. When I unplugged the monitor and tried to go back to just the lcd screen, now I have nothing – black screen. I tried removing the battery and ac power and pressing the power button for a minute. After I put everything back, I turned it back on – still black. I removed the screws that held the top half of the laptop (kb, screen, touchpad, etc…) to the bottom to try to see where the screen connected to the main board. I removed and reseated the cable, verifying that there were no bent pins and everything lined up. When I put everything back together and tried turining it on nothing – still black. I checked the cable again – no bent pins and everything was aligned – still black.

I know the problem could be the screen, the inverter, the cable or the mobo. Since I have a limited income and if I tried all 4, I would be at the cost of a new laptop. Can anyone help?

hi I dropped my laptop bought a new screen and replaced it and it just shows a white screen I took it apart again and saw damage to the data conenction ribbon how much about isit to repair thanks

Ive got a Hi-grade EAA-89 laptop a few days ago. when i switched it on the screen just went white with a few vertical white lines across the screen after i leave it on for a few mins, the screen seems to split into two halves one being white and one dark grey/black.

2) during the boot up procedure if i press FN+F3 with an external monitor plugged in it will switch over to the other monitor however the picture seems fuzzy sometimes with random distortion shooting across the screen for a few mins but then windows runs fine.

3) But if i press Fn +F3 with no monitor connected then it seems to switch over somehow and display the picture, however this only lasts during the DOS/BIOS selection (ie: how do you wish to start windows………..) as soon as i select any option to get into windows then it goes white again ????

I PHONED A FEW COMPANIES WHO IMMEDIATELY TOLD ME IT WAS THE SCREEN BEFORE LISTENING TO ALL THE SYMPTOMS WHICH TELLS ME THEY WANT £150 OUT OF MY POCKET, SURELY IF THE SCREEN WAS DEAD I WOULD NOT BE ABLE TO VIEW THE DOS BOOT SEQUENCE? I WAS THINKING IT MIGHT BE THE POWER INVERTER BOARD IE: IF WINDOWS TRYS TO DRAW MORE POWER THEN IT CAN PRODUCE, OR POSSIBLY THE GRAPHICS CARD THAT WOULD EXPLAIN THE FUZZY BITS WHEN AN EXTERNAL SCREEN IS CONNECTED.

I have a question about what to do with an LCD that will not display. I have a Compaq v2424nr and my LCD stopped working, but if I plug in an external monitor it works fine.

If I tap on the button that puts the computer into standby when you close the lid the LCD screen blinks to the tapping of the button, it tries to turn on but won’t and the screen looks ok (a little reddest as it flickers). I have changed the settings for the display and nothing works.

I have read through the guides and I am ready to tackle the repair, but where to start? I took the computer into a shop and for $40 they said it was the LCD and could replace it for $525 (way to much).

Not knowing what to do I took the laptop apart (nothing broke). I checked the connections for the video card, video cable and inverter, they all looked fine. Nothing looked out of the ordinary, no burnt cards, smells or blackened areas.

I checked the standby button (lid close button) to see if it was dirty or loose. The rubber extension for the button was clean and the switch itself does not seem loose at the circuit board. But if I play with the switch (tapping it down) I can get the screen to flicker.

If I tap on the button that puts the computer into standby when you close the lid the LCD screen blinks to the tapping of the button, it tries to turn on but won’t and the screen looks ok (a little reddest as it flickers). I have changed the settings for the display and nothing works.

You mentioned that the screen turns on for a moment and it has reddish tint, right? It tells me that most likely you have a problem with the backlight lamp but I cannot be sure without testing the laptop with a known good inverter.

You said the repair shop quoted you a new screen, apparently it’s a problem with the backlight lamp which is located INSIDE the LCD screen. I assume they already tried a new inverter, you can ask them. Most repair shops will not replace backlight lamps and they quote you a new LCD screen instead.

If you have no experience, there is a really good chance to damage the LCD. But if your repair is successful, it will cost you less then $20 instead of $525. Proceed on your own risk.

I have an older laptop (Gateway SoLo), the connector to the LCD was a different size so I couldn’t try that without taking the LCD apart further (i didn’t check to see if the cable to the notebook card was the same, figured it was also different).

Yes the screen flickers (only for a second) as the laptop is turning on or switching between displays, and as I play with the switch. I did call the shop after I found out there was an inverter and bulb that could also be wrong, but they didn’t remember if they checked the inverter, just said they found the LCD bad…

Don’t have any problem with replacing the bulb (downloaded the guide), I just need some advice on where to start so I don’t purchase something not needed. It does seem to be the inverter or bulb.

when you said you have a test LCD does it have to be the same LCD what matches the model of the laptop or can you use any laptop LCD to test these problems

i have a problem with an Acer Aspire 3610 screen, when i switch the computer on the screen goes full white and then fades into the normal view slowly and with blotches, and the mouse arrow cursor moves really slowly, here’s a video of waht i mean: http://uk.youtube.com/watch?v=8QqJ-21yCJc

He is still working perfectly as long I DO NOT MOVE THE LAPTOP OR THE SCREEN. THEN THE SCREEN IS BECOMING OF DIFFERENTS COLORS WITH LINES OR SQUARES, WITH OR WITHOUT THE POINTER APPARENT ON IT. SOMETIMES THE SCREEN TURNS BLANK.

I CONNECTED AN EXTERNAL MONITOR AND IT WORKS FINE (TOGETHER WITH THE LAPTOP SCREEN) AS LONG I DO NOT MOVE THE COMPUTER OR THE SCREEN OF THE LAPTOP. THEREFORE I PRESUME THE PROBLEM IS NOT IN THE SCREEN OF MY LAPTOP.

I presume the fault is coming from a short or a loosed connection between the SCREEN and the COMPUTER (because of many years of opening and closing the laptop) or A LOOSE CONNECTION IN THE MOTHERBOARD (VIDEO/VGA).

No Paul I have an older Laptop (Gateway Solo from the mid 90’s) and my current laptop is a Compaq V2424 from @2003. I am asking if the Inverter/bulb would be the same for testing.

I would hate to take the new laptop apart to replace the bulb and find it’s not the problem. But I would realy hate to try the inverter and it messes up the new laptop…

HI, my sony vaio VGN-CR25G laptop LCD screen turned completely white. But I’m sure that the OS is running, Keyboard is working; everything else is working except the LCD screen.

Unfortunately, I cannot tell which one is bad without testing the laptop with a known good screen. One day we had two laptops in our shop failing exactly the same way as yours. One of them had a problem with the LCD screen and the second one a bad motherboard.

Hi, I seem to be having a similar problem. My screen is completely white but when I put pressure on the top part of the laptop screen (where I’m told the connectors are) I can get an image on my laptop. It is too painful to keep putting pressure with one hand on the top part of the screen. Do you think this is simply a problem with the connection? Everything else works fine as I am actually using my laptop and typing this with one hand.

I have a similar problem to Joseph, in that squeezing the plastic on the sides of my Inpiron E1505 LCD fixes the problem, for a while. It seems to happen randomly – the image will fade away to white, sometimes slowly, sometimes more quickly. Rocking the LCD screen back and forth or squeezing the sides seems to help. Any ideas?

Nope, the model was different but it looked very similar to the original LCD installed into the laptop. Same size, same type of connector on the back. It just happened that I had that cracked screen under my bench.

I have the exact same problem as Joseph. It seems like it is a connection problem. As far as a way to put a band-aid on the problem, you can get something like a thin piece of metal, and bend it into a vice, and slide it on to keep constant pressure. It works for me, but I am looking for a more permanent solution. I use a PCI slot dust cover. Cheap and effective.

Yep, it might work as a temporary solution. Also, you can use a piece of pen eraser and placed it inside the display assembly between the LCD screen and cover. When you assemble the display back together, the screen cover applies pressure on the LCD screen because there is a piece of per eraser between them. Might work too.

I have a similar problem where my toshiba M302 screen goes totally blank or the picture becomes unsteady. When I use pegs to hold the sides it becomes temporary steady.When I remove the pegs, it goes blank again. As a lay person, I was told it was a fibre problem. I am yet to find a solution to it.

I have a customers Vaio CR510e. The LCD is white with little black spots. When you lightly tap the LCD you can see video. Connected to an external monitor everything works fine. What do you think? Someone suggested the video cable from the MB to the LCD.

I started without this guide. (Headstrong and have issues with instructions >.>) Halfway through I decided it might be a great idea to have a diagram displaying and informing about what I was looking at.

Over the course of a few weeks, my LCD display has been acting off. I could turn the computer on, but whenever the screen refreshed completely, it would come up white with faded lines. Sometimes, depending on the angle of the lid, the screen wouldn’t come on at all.

good day i need help.. i have compag presario 2100. the problem is when i turn on the screen appear pure white but after 15minutes waiting i see on screen working fine but if i restart it back to white again then wait another 15minutes.. i check all the video cables but it plug properly.. thank you please reply

Im in a bind. My screen is completely white. I have the toshiba satellite. Can u help me fix the problem because, i have so much memory on it. For me just to take it to a computer repair store is 100.00. Thats for the estimate. And no telling how much to fix the screen. I really do not want another laptop. I love this one. Please help me out of this crisis.

I have a Sony VGN-S150 laptop. One day when i pressed the power button, the screen went “white” (gray-bright actually)and held there,HDD still running, nothing else, and my laptop could not start, even the boot logo.

But the interesting thing is, when the laptop not responding, if i turn off (by press-n-hold power, wait for HDD stops) and then turn on immediately, it will work as normal ( boot, starting windows,…), but the screen gets white again if at screen saver mode (turn off display).

I have a compaq presario 1500, the monitor is white but works with a external hooked up. How do I fix this problem? I see someone fixed it but was still white and the screen needs replacing. But I need to make sure if it can be hooked up on the inside first. This would help very much. Thank you for reading this.

THE main PROBLEM: OK i have an inspirion 1520 with 8600mgt. i was playing a video game but then my graphics drivers crashed, so i went to start> shutdown and i restarted the computer. when i turned it on again everything was ok so i turned on the game again. this time graphics driver crashed again but this time i had to shut down by holding down the power button for 10 seconds. now when i restarted the computer, the screen is BLANK AND BLACK, nothing shows up..no bios boot page, no windows logo, nada. i reckon that the system still runs b/c i can still hear the windows sound when i log into my account (yes i logged on blindly). also i can turn up and down the brightness, but i just can’t see anything, CAN ANYONE PLEASE HELP ME? i update my computer regularly and had the newest bios, i was running windows xp sp3/

ANOTHER PROBLEM: so alot of people from other forums are saying its my gpu, but here is the other problem, MY DELL WARRANTY EXPIRED. is there any way for me to replace my 8600mgt with another 8600m gt? i can’t send it to dell cause my warranty expired. i looked at the online manual and it seems like you could take out the 8600m gt on the inspiron 1520 with ease, but my problem now is finding another 8600m gt that is compatible with dell. i’ve googled and found nothing, DELL does not have one neither. does anyone know any place where i can get another 8600m gt card and remember my comp gpu is not mxm. anyone know any sites?

my DELL WARRANTY EXPIRED 5 MONTHS ago, is it possible to still extend my warranty? i haven’t played my laptop the whole before it crashed. i only turned it on for 30 mins and i noticed that it was running hotter than usual and i checked the temps and noticed that the 8600m gt gpu was really hot, THEN BOOM NOW I CAN’T SEE ANYTHING ON MY COMPUTER. PLEASE HELP PLZ.

In order to confirm that you’ll have to test your laptop with an external monitor attached to the VGA ports. Can you get video on the external monitor?

I have HP Pavilion ZD8000. it boots Ok but there ia 3inch vertical line to the left of screen. After copmletion I can see WindowXP logo and finaly for moment or two I can see mosuse pointer the the screen goes completely white. I have tried external monitor and it shows some red and orange bars. Can you help me as if motherboard was faulty, I should not get all bootup info, windoXP logo etc. Please can you diagnose from this info , problem with my laptop. The inverter works OK.

When you connect an external monitor and use the function keys to toggle, does this work before logging into windows? I thought you would have to be logged into windows for the function keys to work but from your photos it looks like you have the boot sequence showing up on the external monitor….laptop in my case is a HP Compaq M2045.

It hasn’t got a white screen but it has developed a thin vertical line an inch in from either side of the screen which is various colours depending upon the background colour. Thinking it might be the cable or possibly screen, but getting an external monitor would be cheaper than replacing the laptop screen…but if the screen eventually dies completely, would want to know that the external one will work without needing to get into windows first…

I think it depends on the laptop brand and model you have. On some laptops you can toggle in BIOS, in other laptops you have to wait until it boots into Windows.

I’m actually asking this on behalf of my Mum who doesn’t live near me so I haven’t actually seen the screen. Yes it sounds like she has a 1 pixel line down the screen – two of them either side. I thought it might have been the cable, but perhaps it is the screen. She is taking it to someone to look at today. I thought I’d ask about an external monitor as getting the internal laptop one is going to be expensive as it has to come from overseas…she hasn’t got access to an external monitor otherwise I would already have got her to try, hence my question.
